1. What is the process that the Assessor uses to establish the base year value of on-campus housing subject to a 35+ year, long-term lease?

In accordance with Proposition 13, the assessed value for a home is the prior year’s assessed value adjusted for inflation up to 2 percent. However, if there has been a change in ownership or completed new construction, the new assessed value will be the market value of the property as of the date of the ownership change or new construction. When a home is acquired, subject to a lease with Stanford, the leasehold interest is the equivalent of ownership of the property. This is legally known as “fee simple interest” when the contract period exceeds 35 years. The law requires the Assessor to treat the leaseholder like all other homeowners. The law states that both the leaseholder and all other property owners effectively have the same property rights. When a transfer occurs, triggering a change in the fee simple ownership interest, it requires the Assessor to establish a base year value for property tax purposes per Revenue and Taxation Code section 110.1 and Property Tax Rule 462.100. The base year value, established because of the transfer of ownership, is set at the Fair Market Value of the property as it is defined in Section 110 of the Revenue and Taxation Code: “as the amount of cash or its equivalent that property would bring if exposed for sale in the open market …” Section 110(b) states that “For purposes of determining the “full cash value” or “fair market value” of real property, other than possessory interests, being appraised upon a purchase, “full cash value” or “fair market value” is the purchase price paid in the transaction, unless it is established by a preponderance of the evidence that the real property would not have transferred for that purchase price in an open market transaction.” If the Assessor can demonstrate that the property would not have sold for a nominal sales price because it was not an open-market transaction, the property is assessed at its fair market value as determined by the value of homes in the greater Palo Alto community. Consequently, the Assessor must consider the greater Palo Alto market for comparable sales that have been exposed to the open market to complete an appraisal of the fair market value of Stanford housing units.

2. Is it possible that the purchase price between Eligible Persons could ever be indicative of fair market value and establish the base value for property tax purposes?

Yes, it is possible, but coincidental that the Assessor could enroll the purchase price for a long-term leasehold interest as establishing the base year value. See below, the example of a chart showing actual data from the Assessor. However, the acceptance of that purchase price would only result after the Assessor had completed an appraisal of the property, based upon comparable sales that had been exposed to the open market and led to a conclusion of market value. This coincidence is most likely to occur for properties at the lower end of the market, where eligible persons have similar purchasing power as participants in the greater market.

3. Can new faculty purchasers challenge the Assessor’s assessments?

Faculty has the right to appeal its newly issued assessments by filing an Assessment Appeal Application with the clerk of the local Assessment Appeals Board (AAB). Assessment Appeal Applications must be filed within 60 days of the mailing date of any notice of the newly issued assessed value (i.e., a supplemental or escape assessment). The Assessor's annual assessments can also be appealed by filing an Assessment Appeal Application between July 2 through September 15 of each year. A separate application must be filed for each year the assessments are being disputed. Applicants must strictly adhere to these filing deadlines and are encouraged to retain proof of timely filing. Assessment Appeal Applications for residences can be heard by either a three-member local Assessment Appeals Board, or by a hearing officer designated by the Assessment Appeals Board. Decisions of the Assessment Appeals Board, or hearing officer, are appealable to the California courts. The courts are required to give great weight to the Assessment Appeals Board's determinations as to value, and may only overturn them if the court concludes that the Assessment Appeals Board had no substantial evidence to support its value determinations. For additional information about Assessment Appeal Applications, see the California State Board of Equalization's Publication 30 (Residential Property Assessment Appeals) available at https://www.boe.ca.gov/proptaxes/pdf/pub30.pdf. Stanford assessments have been contested multiple times, and twice have had a full hearing. In one instance, the AAB upheld the Assessor’s determination of the fair market value of the property. In another case, the AAB raised the value above the Assessor’s recommendation.

The University and Faculty Staff Housing remain committed to supporting its faculty and continue to strive to find innovative ways to provide affordable housing in this challenging climate. Faculty Staff Housing has updated its website, disclosures, purchase contracts and related documents to educate faculty regarding the obligation, per the California Revenue and Taxation Code, of the Assessor to assess property at its fair market value, regardless of the private restrictions inherent in the Stanford Faculty Housing Program. Faculty Staff Housing is working with the Affordability Task Force. This Task Force has been tasked with developing and presenting recommendations aimed, in part, in assisting Eligible Persons to understand and anticipate their property tax obligations and longstanding assessment practices. These recommendations will be provided to the Steering Committee at the end of summer 2019, and presented to the Board of Trustees in December 2019. As a result of Faculty Staff Housing's collaboration with the Affordability Task Force, faculty who purchased their homes before January 1, 2019 and receive above purchase price reassessments, are eligible to receive up to $10,000 a year for two years to cover the property taxes owed on the above purchase price assessments. As part of this program, faculty receiving above purchase price assessments have been offered one-on-one consultations with a licensed real estate appraiser or Faculty Staff Housing personnel to help explain the property tax assessment process. Faculty Staff Housing has connected faculty with property tax consultants capable of pursuing an appeal to challenge the Assessor's new assessed value determination on the property. At the Assessor's suggestion, Faculty Staff Housing is launching an appraisal program whereby any new listings of homes for sale in the subdivision would receive a “fee simple” appraisal of the property. The appraisal will be provided to the seller and potential buyers to assist the parties in understanding the Assessor's likely assessed value for the property following the transaction. The appraisal will also be provided to the Assessor's Office. This appraisal report will be provided at Stanford's cost, and will be folded into the process of listing properties for sale in the subdivision.

5. If faculty only own leasehold interests, how can the Assessor base the faculty's property tax assessments on the value of the entire “fee simple interest” in the property?

The appraiser must determine the fair market value of the unrestricted fee simple estate, unencumbered by leases, based on the highest and best use of the property (AH 501). Private parties cannot reduce the taxable value of their property by imposing private restrictions. Only enforceable government restrictions are recognized as limiting the full fee simple interest, per R & T 402.1.

6. How can I anticipate the property tax obligation associated with my long-term leasehold interest in Stanford property?

The amount of property taxes faculty would be required to pay depends on the Assessor’s determination of the market value of the property. In any case, the property tax rate varies by tax year, but is generally around 1.15%. So, for example, if the Assessor’s market value conclusion is determined to be $1.5M, then the annual property tax would be $17,250. For further information regarding property tax obligations, please review the Assessor’s website at https://www.sccassessor.org/. And to learn about supplemental assessments, please see the following informational video https://youtube/-v6q-4KGqdM&feature=player_embedded.

7. Tell me more about Faculty Staff Housing’s new program to commission fee simple appraisals on properties listed for sale. What is the purpose of this new requirement and how will it work?

Market value appraisals will assist Stanford faculty and staff understand market realities. The purchase price is not necessarily reflective of market value and that they may end up with an increased assessment and tax bill. The Assessor has advised that the best way for Eligible Persons to anticipate their base year determination is to obtain a fee simple appraisal at the time the transaction closes. Faculty Staff Housing has carefully considered the Assessor's recommendation and has agreed to provide the requested appraisals to the buyer and the Assessor. These appraisals will not be binding on the Assessor. Under the program, sellers will notify Faculty Staff Housing of their desire to list their residences for sale. The seller will be required to select a licensed real estate appraiser from Stanford's preapproved list. Faculty Staff Housing will then commission the appraisal report and will cover the cost of the report. Subsequent appraisal reports will be the responsibility of the requesting party. The seller will be given an opportunity to review the appraisal report for any material errors before it is finalized. Faculty Staff Housing will provide the seller with a copy of the final appraisal report, which is expected to take approximately 30 days to complete from the date it is commissioned

Whether they are called “Granny” or “In-Law” Units, Accessory Dwelling Units (ADU’s), are one of many solutions chipping away at California’s challenge of providing affordable housing, which has reached crisis proportions in Silicon Valley.

When homeowners contemplate building an ADU, often to realize a second income, they want to know will my property taxes go up? The short answer is yes, but only on the marginal value of the ADU. Assessors throughout California treat ADU’s like a home addition. The existing home will not be reassessed. The most recent changes in laws, as of 2019, do not change the way ADU’s are assessed.

There are a few variations of ADU’s. The most common is a new structure separate from the primary house, typically with a private entrance, kitchen, and bathroom. The new construction on the ADU will be assessed at market value as of the date of completion, or as of the January 1 lien date for partially complete construction.Typically, Assessors use either the cost of construction or a market-based sales comparison to value the new improvements separately. This new assessment is added to the existing assessment.

Homeowners may not want to add a separate “Granny” Unit, but instead prefer to convert a large family room or garage into an ADU. Though no new square footage is added by a conversion, any alterations of the existing living space will be assessed at market value.

For example, if new heating, bathroom, or kitchen fixtures are added, the cost will be added to the existing property tax base of the area that is modified. Other areas of the home untouched will not be reassessed by the Assessor. However, if the area modified is “taken down to stud walls,” making it substantially equivalent to new, it may be reassessed as new.

Whether the addition is for a parent or rented to earn a little extra income, the Assessor’s determination of the new assessed value remains the same, and is treated like any other addition to a home.

Should a homeowner disagree with the Assessor’s new assessed value, there is a simple and free process to dispute the added value. It is always best to start with the Assessor’s staff. An informal review process is available to resolve any factual issues that may exist in the assessment.

It is important that property owners contact the Assessor’s office within 30 days of receipt of the annual, supplemental or corrected assessment notice before deciding to file a formal assessment appeal. Many times, a simple discussion regarding the basis for the Assessor’s decision, the information needed by the Assessor, or to resolve misunderstandings of law is all that is needed.

Authored by Assembly Member Phil Ting, Assembly Bill 551 created the Urban Agriculture Incentive Zones (UAIZ) Act which promotes small-scale commercial or noncommercial agricultural use on vacant, unimproved or blighted lands in urban areas. Adopted in 2013, AB 551 allows cities and counties to create UAIZs, offering preferential property tax assessment to owners of eligible urban lots who agree to enter into a contract restricting the property use to small-scale production of agricultural crops and animal husbandry for a period of five years

About Prop 8

Proposition 8 was passed in November 1978 as an amendment to Proposition 13 and implemented as Revenue & Taxation Code Section 51(a)(2). It annually caps the assessed value of property as of the lien date (January 1) at the lesser of its market value or its factored base year value.

HOW IT WORKS

Proposition 8 allows a temporary reduction when the market value of property has fallen below its factored base year value as of the January 1 lien date. Once a Prop 8 reduction has been enrolled, the property’s assessment must be reviewed annually to ensure that the lesser of the market value or the factored base year value is enrolled.

The property’s base year value continues to be factored at a maximum two percent per year, setting its maximum assessed value. As the market recovers the market value of a property will increase based on market conditions which are not restricted to a two percent growth. The value enrolled will follow the market growth rate until the market value exceeds the factored base year value and the lower factored base year is enrolled.

Factored base year value: the value established as of the date of acquisition and/or completion of new construction. This value is adjusted each year by an inflation factor. The inflation factor is the lesser of 2% or the California Consumer Price Index (CCPI) rate.

The Process

The Assessor annually sends Notifications of Assessed Value at the end of June, notifying property owners of the intended assessed value for that roll year. It provides property owners the opportunity to compare that assessment to their opinion of market value as of January 1. If the assessed value is greater than the market value of the property as of January 1, the property owner may request a review for a Prop 8 temporary reduction. There are two separate review processes: Informal Review and Formal Appeal/Assessment Appeals Application.

If you did not receive the Notification of Assessed Value Letter after the second week of July, you can request a duplicate notice be mailed to you by requesting online, contacting the Santa Clara County Assessor’s Office at This email address is being protected from spambots. You need JavaScript enabled to view it. or 408-299-5500.

Informal Review

The Notification of Assessed Value is mailed last week in June

The filing period starts June 30 and ends on Aug 1

The Assessor’s Office reviews Prop 8 requests through August 15. The results of the reviews are sent shortly after August 15.

Regardless of the result of the Assessor’s review, the property owner is entitled to file an Assessment Appeals Application. It is the property owner’s responsibility to timely file an Assessment Appeals Application if dissatisfied with the Assessor’s informal review.

Formal Appeal or Assessment Appeals Application

An Assessment Appeals Application can be filed through the Clerk of the Board between July 2 and September 15 (or, if September 15 falls on a weekend, the following Monday)

The Assessment Appeals Application is available from the Clerk of the Assessment Appeals Board via their website or you can contact them directly at 408-299-5088, for more information

Assessment Appeals can take up to two years to resolve. Once an application is submitted, the assigned appraiser may contact the applicant to discuss the appeal.

Who Should Request

The example below shows when a property owner would qualify for a temporary reduction.

In the example a property owner purchases a property at fair market value for $800,000 establishing the base year value at year 1.
On the subsequent lien date (year 2), the market value decreases to $750,000, but the property owner‘s assessment is based on the factored base year value, $816,000 ($800,000 plus 2%) which is higher than the market value. Therefore, the property owner would qualify, under Prop 8, for a temporary reduction to $750,000.

In this case, the property owner would qualify for a Proposition 8 reduction, for years 2 through 6, but not in year 7.

Note: In year 7, the factored base year value, $900,930, would be reinstated and the property owner would not qualify for relief under Prop 8

The red line: the “market value,” the current market value based on sales of comparable properties as of January 1 of that year.
The blue line: the “factored base year value,” purchase price plus no more that 2% factoring per year.

Who Should Not Request

The example below shows when a property owner would not qualify for a temporary reduction.

Typically, this is the case when the market value increases after the property is purchased.

If a property owner purchases their property at fair market value for $500,000 this establishes their base year value at year 1. In year 2, the market value increases to $550,000, but the property owner‘s assessment will still be based on the
factored base year value
of $510,000 ($500,000 plus 2%) which is lower than the market value.

In this case a property owner would not qualify for a Proposition 8 reduction, the factored base year value is still much lower than the current market value of the property.

Note: Even if the market has gone down, your factored base year value can still be below the current market value for that year as shown in years 5, 6, and 7 below.

The red line: the “market value,” the current market value based on sales of comparable properties as of January 1 of that year.The blue line: the “factored base year value,” purchase price plus no more that 2% factoring per year..
